In Canada November 12, 1934 1 Claim.

This invention relates to certain improvements in shower bath installations and has, for one of its objects, the provision of an economical installation in which a rigid iron or porcelain show 5 basin is provided with a tile or composition flooring presenting a non-skidsurface which effectively eliminates accidents due to slippage of the feet on the bottom of the basin.

Another object is the provision of a generally improved shower bath installation including a slip joint between the basin and the wall finish of the shower room or compartment which permits the basin to follow the settling movement of the fioor on which it is supported without subjecting the wall finish to damaging strains.

The foregoing and other advantageous features of the present invention will be more readily understood from the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a view, partly in perspective and partly in section, of a shower bath installation designed in accordance with this invention.

Fig. 2 is a vertical sectional view through a portion of the installation appearing in Fig. 1.

Referring more particularly to the drawing, 5 designates a relatively strong and rigid enamelled iron or porcelain shower basin resting directly on the floor of a shower room or compartment 6. The bottom of the basin presents a recess 1 containing a concrete filling 8 in which carborundum or other suitable composition tiles 9 are embedded to provide the basin with a fioor presenting a non-skid surface, which eliminates accidents due to slippage. The tiles 9 are preferably laid so that the non-skid floor surface slopes downwardly from the marginal edges of the recess 1 towards a drain pipe i fitted in a central opening of the basin that is bounded by an upright wall II. The upper end of pipe I0 is provided with a flange l 2 which is clamped firmly against a gasket I3 on the wall I l by screwing the lower portion of pipe l0 into a drain conduit I 4. The upper end of conduit l4 terminates in a flange l5 bearing against the bottom of the basin.

The marginal wall of the basin terminates in an outwardly directed rim l6 underlying an angle frame I! attached to the studding H3 at the lower edge of the wall finish i9 which is applied to cover the studding of the room or compartment 6 above the basin 5. This wall finish l9 may be plaster or any other approved construction but is herein shown as comprising a rough cement foundation 20 faced by suitable wall tiles 2 I.

It is desirable that the basin 5 be free to move relatively to the studding l8 and the wall finish H9 in response to sinking or settling of the floor on which the bottom of the basin is supported. According to the present invention, this is taken care of by the provision of an expansion joint between the wall finish and the basin which also prevents leakage of water through the gap left between the basin rim l6 and the angle frame ll. As here shown the expansion joint is formed by a single course of substantially L-shaped tiles 22 presenting horizontal portions 23 and vertical portions 24. The horizontal portions 23 are embedded in the rough cement wall 29 directly beneath the lowermost wall tiles 2|. The vertical portions extend downwardly below the angle frame I! into the upper portion of the basin 5 and are positioned close to the inner surface of the marginal wall of the basin to provide a slip joint which permits the basin to have a substantial range of free vertical movement withoutdanger of leakage of water through the gap between the basin and the angle frame I! of the Wall finish.

The provision of a slip joint between the wall finish and the basin, as herein described, is a very important feature of the present invention since it eliminates cracking strains to which the wall tiles 2! and the tile floor of the basin would otherwise be subjected in response to sinking or settling of the floor on which the basin is supported. If the rim of the basin were cemented or otherwise attached to the wall finish [9 it is obvious that the latter would also be subjected to cracking strains by the weight of a person standing in the basin if there is any clearance left below the bottom of the basin by the settling of the fioor. The presentinvention avoids this difficulty since the basin, as installed in accordance with this invention is free to move downwardly with respect to both the studding l8 and the wall finish l9 so that the bottom of the basin always rests flatly upon and is adequately supported by the underlying wall of the shower room or compartment.

Having thus described what I now consider to be the preferred embodiment of my invention it will be understood that various modifications may be resorted to within the scope and spirit of the appended claim. For example, the particular type of slip joint herein shown and described may be replaced by any other form of slip joint capable of accomplishing the same result. It will also be obvious that the novel features of the present invention are not limited to shower bath installations but may also be used to advantage in connection with the installation of bath tubs or the like.

Having thus described my invention, what I claim is:-

A bath installation comprising a bath compartment, a rigid shower basin resting directly on the floor of said compartment, the bottom wall of said basin being recessed and provided with a central opening bounded by an upright wall spaced from the outer margin of the recess, a

'tile floor inlaid in the recess to fill the space between the outer margin of the recess and said v upright wall, the upper surface of said floor being sloped downwardly toward the central opening;

a drain pipe extending downwardly through said opening and provided, at its upper end, with a clamping flange overlying the upright Wall surrounding said opening and a drain conduit into which the lower end of said drain pipe is screwed so that the upper end of the conduit is clamped against the bottom wall of the basin, a wall finish applied to the sides of said compartment so that the lower edge of the wall finish overlies the rim of the basin and means forming a slip joint between the basin rim and the overlying edge of the wall finish.
